Hi, @pcd1193182
so, I added a test case to ztest that uses dmu_free_long_range() to punch
various large holes in objects. That test case asserts as:
```
ztest: ../../module/zfs/dbuf.c:3270: Assertion `db->db_blkid <=
dn->dn_phys->dn_maxblkid >> (db->db_level * epbs) (0xa3bd0 <= 0x3e8d6)' failed.

```
without the fixup of the maxblkid in dmu_write_ready() that I mentioned above.
